Alva'l l Cremean,.S earcy, v Application November 29, 1943, Serial'No'.'6 2 ,44 1 1 Claim. (01. sg 'sm- 7 l i invention relates t'o an internal combustion engine, and more particularly to a turbulence manifold for interposition between the intake manifold and a pair of carburetors.

The object of the invention is to provide a turbulence manifold for interposition between the intake manifold of an internal combustion engine and a pair of carburetors which will insure that the air-fuel mixture will be transmitted to the combustion chambers in its most efficient vaporized state with increased velocity.

Another object of the invention is to provide a turbulence manifold for an internal combustion engine which will give the engine superior motor performance at all speeds, and which will decrease fuel consumption without sacrificing any of the other added engine performance.

A further object of the invention is to provide a turbulence manifold which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure l is a plan view of a turbulence manifold according to the present invention, showing the adaptation thereof with respect to a pair of carburetors and the intake manifold of an internal combustion engine;

Figure 2 is a side elevational view of the turbulence manifold;

Figure 3 is a sectional view taken on the line 33 of Figure 4;

Figure 4 is a sectional view taken on the line 4-4 of Figure 3;

Figure 5 is a plan View of the blanks from which the deflector plate is made.

Referring in detail to the drawings, the nu.- merals I and I l designate a pair of conduits leading from a pair of carburetors for conveying a fuel-air mixture from the latter. The numeral l2, Figure 1, designates a portion of an intake.

manifold of an internal combustion engine. Interposed between the conduits I0 and H and the intake manifold I2 is a turbulence manifold [3 through which the air-fuel mixture from the carburetors passes prior to its entry into the intake manifold 12.

The turbulence manifold [3 comprises a hollow housing substantially cylindrical shape in cross section having its opposite ends l and I6 open and registering with the conduits l0 and l I. For securing the end l5 of the housing to the conduit [0, a transverse apertured mounting face or plate I1 projects from the end P5 of the housing" and rarranged 'in opposed relation 'withre'spect'to a mounting face I8 on the conduit l0. Suitable bolt-and-nut assemblies l9 connect the mounting faces or flanges l1 and I8 together. The other end 16 of the housing I4 is secured to the conduit l l by a transverse apertured mounting flange or plate 20 which is arranged in opposed relation with respect to a mounting plate or flange 2| on the conduit l l and connected to the latter by bolt-and-nut assemblies 22. I

Arranged intermediate the ends of the housing H is an opening 23 which registerswith the intake manifold I2 and permits the air-fuel mixture to enter the latter. The housing [4 is provided with a mounting plate or flange 24 adjacent the opening 23 and the plate 24 is apertured, as at 9, for receiving bolt-and-nut assemblies 25 in order to secure the housing M to the intake manifold [2. The housing I4 is provided with a means for setting up a predetermined pattern of accelerated turbulence in the air-fuel mixture prior to its entry into the intake manifold [2. This means comprises a deflector plate 26 substantially S- shaped in cross section arranged within the housing l 4 and provided with a transversely-disposed apertured tab 21 for receiving a screw 28 tofasten the plate 26 to the housing I l. The plate 26 is formed with a web having its ends bent or curved in opposite directions as at 29. In Figure 5, there is shown the blank 30 from which the deflector plate 26 is made. Thus, there is shown the apertured tab 21 which is bent along the line 3|, and V the end portions 29 thereof which are adapted to be bent in opposite directions along the line 32.

By using the turbulence manifold with dual carburetors, the thrust augmentation on all makes of car and truck engineswill be increased. The deflecting plate 26 eliminates wet spots in the air-fuel mixture which passes through the housing l4. Further, the plate will set up a predetermined pattern of accelerated turbulence in the air-fuel mixture, so that it will be transmitted to the engine combustion chambers in its .most

efl'icient vaporized state with increased velocity. The plate 26 deflects each air-fuel stream downward, and at the same time breaks down the fuel into more minute particles giving superior motor performance in all respects.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

' attaching flanges on the ends and with said flanges positioned in a common plane which plane is parallel to the longitudinal axis of the housing, the axes of said carburetor openings being substantiallyperpendicular to said axis of the housing, said housing also having an outlet intake manifold opening with an attachingv flange thereon positioned between said carbu-' retor openings, the area of said housing being less at the point where the intake manifold opening is positioned than at the ends where the carburetor openings are positioned, and a deflector, substantially s-shaped in cross section, having an intermediate web positioned transversely of said housing and having oppositely curved ends on said web mounted on the inner surface of the wall of the housing opposite to the 4 wall in which the said intake manifold opening is positioned, said deflector positioned in alignment with said intake manifold opening whereby maximum turbulence of air and gas mixtures passing through said housing is produced.
